2018 Mazda Mazda6 Complaints

At less than 95,000 miles, the car suddenly started overheating. Coolant level was fine, maybe ever so slightly low (could still see the coolant in tubing and some in reservoir, which was closer to low than full). Replaced ECT sensor, thermostat and water pump which seemed to fix the issue. Drove for 9-10 days with no issues and it started overheating again. I was able to park quickly afterward at work (<10 seconds). Schedule for drop off at dealer (if car didn't show signs of overheating first (would have called tow truck). Checked fluid levels in car (was ~1Qt low) and topped it off. Drove to dealer (~30min ride) with no issues whatsoever. When dealer looked at it, they said cylinder was warped and leaking, requiring new engine. A just paid off car, with less than 100k miles on it, now needs a new engine that will cost more than half of what it's worth.

On [XXX] I purchased a Mazda 6 at Ocean Mazda in Miami, Florida. The car has 18,700 miles. The reason why the car has only 18K miles it's because out of the 4 years we have owned it, it was not used as much as a result of the COVID pandemic and my daughter attending online classes. I have always done timely maintenance services as required by Mazda at our service dealer Ocean Mazda and have proof of maintenance records to confirm the minor maintenance that have been done, oil change, tire rotation, battery replacement and a recall. This past Saturday [XXX] I took our Mazda for an oil change; and I was informed that a Five Point Inspection showed that the Driver Rear brake caliper and pad needed to be replaced because it was measuring 2% lining compared to the three other calipers which showed a 6% lining. Since the 36 month warranty has expired the cost to replace the caliper is $875.20. I'm a mom simply concerned about the safety of my daughter and have zero knowledge about bra...

Noticed slight coolant leak, took car to mechanic, he stated cylinder head was cracked, & causing coolant to spray everywhere. Towed car to dealer. Was given repair estimate of over $11,000, for a new engine. I see a safety bulletin online for my year make & model car. This overheating can apparently cause an engine fire. So far, Mazda seems to be showing negligence & not properly addressing the issue for owners.

Start engine when cold and it knocks/ taps from the valve cover very loud, found a tab for valve lifters. Mazda said I’m out of warranty and it would be a 2k fix on a car I just bought second hand. A lot of other drivers have experienced the same issue and have even said it’s a safety issues as when it happens for long enough it could cause the cams to wear down causing the car to stall out in traffic or in a dangerous road situation. Very dangerous imo and should be fixed for free as Mazda admitted that it’s a design flaw of the HLA

Mazda has a huge issue with there HLAs hydraulic lash adjusters. I've driven the car for 60k+ miles and it's ticked every since I got the car. And many people in the community also have the issue. And Mazda says it's fine and to rev the car above 3k rpms. This issue needs to be resolved. Before my warranty went up they said they'd fix it at the dealer if it would tick while in there possession. That's just not reasonable the tick happened as random as it gets. Please please for the sake of Mazda and all it's owners make Mazda fix this as a recall. Many people in the US would be the happiest people in the planet not having to hear there 20k$ car tick like a broken old piece of junk. Thank you for listening. Your truly a franticly hopeless hard working america with a half broken car.
